In the near future I plan on replacing my 1993 F150 and have been eyeing up 04-08 5.4L F150's. I may be in a position to swing a 2009 4.6L 3V due to the cash for clunkers bill if it does get passed. A 2009 5.4L gets 1 MPG worse (combined) therefore wouldn't work for me considering my "clunker".
Anyways, are there any performance numbers (0-60, quarter mile etc.) out there comparing the two engines in a similar equipped truck (maybe a Scab 4x4)? Or people out there who have gone from the 5.4L to the 4.6L 3V?
I'm thinking the two are very comparable with the 5.4L at 300hp, the 4.6L at 292. The 4.6L is down on torque but maybe the two extra gears make up for it???
I already own a 4.6L 3V in my Mustang that takes me to a 13.5 second qtr mile, but the F150 is a whole different beast!
